The Toshiba Mini NB305 can be considered as a high-end netbook. It replaces the NB305 (N410) as Toshiba's premium netbook. The most notable change between the two models is the addition of dual core Intel Atom N550 processor which replaces the N450 (single core) processor. Unfortunately with the increase in processing capabilities, the NB305's power usage has also gone up; the quoted battery life have dropped from 11hrs to 8hrs and 45mins. Whilst this is disappointing, the new battery time can still be considered as good when compared to similar netbooks. Another area that had received a bump in performance is the memory, previously it had 1GB of DDR2 memory, the NB305 (N600) now comes with 1GB of DDR3 memory. Many components remained the same, this include the 10.1'' LED backlit display, the 250GB hard drive and the Intel GMA 3150 integrated graphics.
